By fighting over whether tablets or PCs are better tools for creating content—as a sort of proxy war over whose vision owns the future of computing devices—we may be overlooking something important: the possibility that these very different devices may simply be good at different kinds of creativity and that their differences may actually complement one other.
In other words, both form factors have creation or production in their DNA, but with very different emphases, contexts, and approaches. The big difference between them is this: the typewriter form factor (that is a the root of the PC) has its roots in creation that is formal, mechanistic, and professional, while people have historically used tablets to create content of a more personal or intimate nature.
Both tablets and traditional PCs have strengths in content creation, but they are strengths of different types. And their different strengths have more to do with the creative process than the content itself.
